_Drepanis_ Temminck, Man. d'Orn. Ed. II, I p. LXXXVI (1820--"Espèces:
_Certhia pacifica--obscura--vestiaria_ et probablement _falcata_, que
je n'ai pas vu.") Type by elimination: _Drepanis pacifica_.
The name _Drepanis_ is now restricted to the practically extinct "Mamo" of
the natives of the Sandwich Islands. _Drepanis pacifica_ has a very
striking black and yellow colouration; the somewhat loose-webbed under
tail-coverts cover about three-quarters of the tail. The bill is long,
curved, non-serrated, the upper mandible a few millimetres longer than the
lower jaw. Nostrils large, covered by an operculum. First primary
rudimentary, hidden by its covert. There is a silky, soft and fluffy
axillary patch of feathers. The tail is slightly rounded. The metatarsus is
covered with large, partly fused scutes.
Only one species known.
